Review on 🚗 The Reliable Denso 234-4650 Oxygen Sensor: Ensuring Optimal Vehicle Performance by Dorian Bharadwaj

Not much to say here. The check engine light indicated a bad O2 sensor, so I had it replaced. A little over a month has passed and no more problems in this regard (knock on wood). It appears to be a quality product. This isn't necessarily related to the product, but if you find you need an O2 sensor. MAKE SURE you find out which ones. You can diagnose the Check Engine Light for free at many auto parts networks (Autozone, Advance Auto, etc.). This diagnostic will tell you (at least mine) which bank and sensor is faulty. Part upstream, part downstream. You are different and you don't want to be wrong. This could be pretty basic information, but I just wanted to throw it in there. If my mechanic hadn't told me exactly what to buy, I might have bought the wrong part. My way of finding this part was to search for "oxygen sensor" on the auto parts chain's website. and find available downstream and upstream products that fit my car. I then took the part number and pasted it here on Revain. And the last word, definitely buy at prices. Some of the things I needed for my car (like a new kill switch. 13 at Revain vs. 28 at the dealer or Autozone) are available from Revain for a lot less than the average store. The rest (new caliper. 50 for Revain vs. 40 for Autozone after core filling) is actually more expensive. Anything with a base fee (basically you have to bring the old one with you if you're buying a refurbished/new one or you'll have to pay more) will likely be cheaper at the parts store if you have the old one to trade in.
